The three-effect evaporator of this design uses the secondary steam produced by the first evaporator as a heating source again, and introduces it into another evaporator. As long as the pressure in the evaporator and the boiling point of the solution are controlled to reduce it appropriately, it can be used The secondary steam produced by the first evaporator is heated. At this time, the condensation of the first evaporator is the heating source of the second evaporator. The direction of access is the second effect, the third effect and so on.

The three-effect evaporator has many characteristics, such as short heating time of the material, fast evaporation speed, large concentration ratio, and effectively maintain the original effect of the material. The energy-saving effect is remarkable, and the evaporation is about 70% less than the single-effect evaporator. The material is evaporated and concentrated in a closed system, and the environment is clean and comfortable.

The application range of the three-effect evaporator is as follows: 1. Concentrate the dilute solution to directly prepare the product or reprocess the concentrated solution (such as cooling and crystallization) to prepare the solid product, such as the concentration of electrolytic caustic soda, the concentration of aqueous sugar solution and various applications. Concentration of kinds of fruit juices, etc.; 2. Concentration of solutions and recovery of solvents at the same time, such as the concentration of organic phosphorus pesticide benzene solution, evaporation of alcohol extracts in the production of traditional Chinese medicine, etc.; 3. In order to obtain pure solvents, such as seawater desalination.

The main features of the three-effect evaporator designed in this way:

1. This equipment is suitable for occasions where the viscosity is moderate, the scaling is not serious, and the corrosiveness is not large. It is widely used in the evaporation and concentration of liquid materials and sewage treatment in the pharmaceutical, chemical, food, light industry and other industries.

2. This equipment adopts the working principle of tube-and-tube circulation external heating. The material in the evaporator has a large circulation rate, short heating time and fast evaporation speed.

This equipment adopts pressurized operation, with large concentration ratio and good wastewater treatment effect.

3. The energy-saving effect is remarkable, and the amount of steam can be saved by about 70% compared with the single-effect evaporator. The three-effect evaporator produced by our company is used in the sewage treatment operation of the maleic anhydride plant, and the steam consumption is as low as 0.1t/t sewage.

4. The equipment adopts a tower structure, which greatly reduces the area occupied, and can save all levels of pumps. The equipment is reliable and stable, and the operation is energy-saving and environmentally friendly.

5. The material of this equipment can be adjusted according to production requirements.
